1. Main forms of lexical cohesion
repetition:
synonyms
superordination: where one word encompasses other meanings (hyponyms)
antonyms
specific-general/ general specific reference (words referring to the same thing or person, but where one provides greater detail than another)
ordered series (words that we recognise as part of a set series minutes, hours,days, week, seasons, etc.)
whole-part relations, where one word names a part of an item that another names in full (apple pips)

2. Grammatical Cohesion
These are the grammatical words (function) words that are used to link sentences across an entire text.
The basic kinds are:
Reference - this tells the reader that they can only make complete sense of the word or structure they are looking at if they look somewhere else in the text to complete the information.
Words can reference forward (cataphoric) or backward (anaphoric) in a text.
Another form of reference is exophoric (this refers to something outside the text, often this is readers themselves – as in the case of 'you' or in the case of the imperative).
The opposite of this feature is known as endophoric when all reference is to items or referents strictly within the text.

3. Main grammatical reference words
Pronouns: (including ‘there’)
Deictics: (e.g. demonstrative pronouns) words that indicate or point out something present in the context.
comparative reference (comparison, comparatives, superlatives)
substitution this where the writer substitutes one item for another (hissing plume deluge).
Ellipsis, in other words missing something out. Surprisingly this can actually help texts cohere because readers themselves fill in the gaps.
conjunctions. As their name suggests, these are in a way the most explicit joining devices of a text. The two basic types are co-ordinating conjunctions, which join clauses of equal rank (and, so, but) and subordinating conjunctions, which join clauses of unequal rank (although, until, when, whether, etc) as.

6. General-specific/superordinator-hyponym
The building was hard to spot among the village cluster of the pub, the shop, and a few cottages, as it is perfectly camouflaged by a limestone façade – a long, low building that is more like an Andy Goldsworthy creation than a hotel.

8. Semantic field: agriculture,geology, vegetation.
The ridges are all stone: thousands of dry stone walls enclosing tiny, empty fields, most cultured by people long gone, and a few still maintained by the island’s diminishing population of around 200.
Other expansive slabs of limestone, too resistant to the traditional farming methods when soil was created from sand and seaweed, still boasts fissures filled with rare, wild flowers.
